我正在尝试让一个.Net 4.7.2 Web应用程序连接到运行在（Windows）Docker容器中的RabbitMQ服务器（与Web应用程序运行在同一台机器上）。

更新：使用非Docker版本的RabbitMQ也不能解决问题。控制台连接到非Docker RabbitMQ并可以发布消息，但.Net 4.7.2 Web应用程序仍然失败。

我使用的是RabbitMQ.Client 6.2.4（VMWare），连接代码如下：

ConnectionFactory connectionFactory = new ConnectionFactory();
Uri uri = new Uri("amqp://dan:dan@localhost:5672/");
connectionFactory.Uri = uri;
var theConnection = connectionFactory.CreateConnection();

(Note我也试过，结果一样：

var factory = new ConnectionFactory() { HostName = "localhost", Port = 5672, VirtualHost = "/", UserName = "dan", Password = "dan" };
using (var connection = factory.CreateConnection())
)

使用者 dan 以管理员身份存在，并拥有虚拟主机的权限。
我收到以下错误：

{"None of the specified endpoints were reachable"}
Data: {System.Collections.ListDictionaryInternal}

TargetSite: {RabbitMQ.Client.IConnection CreateConnection(RabbitMQ.Client.IEndpointResolver, System.String)}

RabbitMQ日志报告此活动：

我创建了一个小的控制台应用程序，该应用程序工作正常-它可以连接（并随后向队列生成一条消息）。
我已经尝试使用我的机器的实际IP地址以及127.0.0.1和控制台连接，但Web应用程序没有。
我看了几张票，心想这也许是个好线索：

这就是说，要确保System.Threading.Tasks.Extension、System.Threading.Channels和System.Memory在所有引用的项目中都是相同的版本，并且它们是。
还尝试使用 rabbitmq_localdev 作为URI中的rabbit主机名。
如有任何建议，我们将不胜感激！
谢谢你，
